Notes

When the time-out value associated with the socket expires, the socket function terminates with the ETIMEDOUT errno code. For more information about socket time-outs, see Associating Time-outs to Sockets.
The following table lists the flags that can be specified. The EQUate symbol is generated by the MSGFLAGS DSECT by the #SOCKET TCPIPDEF macro call and the field names are associated with the SOCKET-MISC-DEFINITIONS.

EQUate Symbol	Field Name	Description
MSG@DROU	SOCKET-MSGFLAGS-DONTROUTE	Send without network routing
MSG@OOB	SOCKET-MSGFLAGS-OOB	Send and receive out-of-band data
MSG@PEEK	SOCKET-MSGFLAGS-PEEK	Peek at incoming data
MSG@WALL	SOCKET-MSGFLAGS-WAITALL	Wait until all data returned

PL/I programs: The SOCKET_MISC_DEFINITIONS is used and the dashes are replaced by underscores.
